Transformation Data Types

Transformation Data Types

The following table describes the transformation data types:

Data Type	Size in Bytes	Description
Array	Unlimited number of characters.	Complex data type. You can use arrays with complex sources and targets.
Bigint	8 bytes	-9,223,372,036,854,775,808 to 9,223,372,036,854,775,807 Precision of 19, scale of 0 Integer value.
Binary	Precision	1 to 104,857,600 bytes You cannot use binary data for COBOL or flat file sources. You cannot use binary data for flat file sources.
Date/Time	16 bytes	Jan 1, 0001 A.D. to Dec 31, 9999 A.D. Precision of 29, scale of 9 (precision to the nanosecond) Combined date/time value.
Decimal	8 bytes (if high precision is off or precision is greater than 28) 8 bytes (if high precision is off or precision is greater than 38) 16 bytes (if precision <= 18 and high precision is on) 20 bytes (if precision > 18 and <= 28) 24 bytes (if precision > 28 and <= 38)	Decimal value with declared precision and scale. Scale must be less than or equal to precision. Precision 1 to 28 digits, scale 0 to 28 For transformations that support precision up to 38 digits, the precision is 1 to 38 digits, and the scale is 0 to 38. For transformations that support precision up to 28 digits, the precision is 1 to 28 digits, and the scale is 0 to 28. If you specify the precision greater than the maximum number of digits, the Data Integration Service converts decimal values to double in high precision mode. For transformations that support precision up to 38 digits, the precision is 1 to 38 digits, and the scale is 0 to 38. For transformations that support precision up to 28 digits, the precision is 1 to 28 digits, and the scale is 0 to 28. If you specify the precision greater than the maximum number of digits, the Data Integration Service converts decimal values to double in high precision mode.
Double	8 bytes	Double-precision floating-point numeric value. You can edit the precision and scale. The scale must be less than or equal to the precision.
Integer	4 bytes	-2,147,483,648 to 2,147,483,647 Precision of 10, scale of 0 Integer value.
Map	Unlimited number of characters.	Complex data type. You can use maps with complex sources and targets.
Nstring	Unicode mode: (precision + 1) * 2 ASCII mode: precision + 1	1 to 104,857,600 characters Fixed-length or varying-length string.
Ntext	Unicode mode: (precision + 1) * 2 ASCII mode: precision + 1	1 to 104,857,600 characters Fixed-length or varying-length string.
Real	8 bytes	Precision of 7, scale of 0 Double-precision floating-point numeric value.
Small Integer	4 bytes	-32,768 and 32,767 Precision of 5, scale of 0 Integer value.
String	Unicode mode: (precision + 1) * 2 ASCII mode: precision + 1	1 to 104,857,600 characters Fixed-length or varying-length string.
Struct	Unlimited number of characters.	Complex data type You can use structs with complex sources and targets.
Text	Unicode mode: (precision + 1) * 2 ASCII mode: precision + 1	1 to 104,857,600 characters Fixed-length or varying-length string.
timestampWithTZ	40 bytes	Aug. 1, 1947 A.D to Dec. 31, 2040 A.D. -12:00 to +14:00 Precision of 36 and scale of 9. (precision to the nanosecond) Timestamp with Time Zone data type does not support the following time zone regions: AFRICA_CAIRO AFRICA_MONROVIA EGYPT AMERICA_MONTREAL
